Business cases for teaching are widely available on the Internet. Many of them come with a fee, but free cases are also available. Although a business case is free, remember to check the user rights.
There are many services on the Internet selling business cases. Usually, a teacher signs in at the service and purchases a case for each student group separately. The library doesn't buy cases. If you are interested in buying a case, please contact your own unit.
